A. 1. Limit background activity for the app. Go to your phone's settings, find the app, and restrict background data usage. This can help reduce battery consumption. 2. Close other apps running in the background that may be using additional resources.

B. 3. Disable any unnecessary features in the app that you do not use, such as notifications or location services, to help conserve battery life. 4. Consider reducing the frequency of app updates or syncing if possible, as these can also drain battery.
